CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 651,117, dated June 5,1900. Application filed September 11, 1899. Serial No. 730,125.(Noimodel.)

To all whom it may oon/cern.:

Be it known that we, ERIC W. PALMQUIs'r and GEORGE G. FLOYD, citizens ofthe United States, and residents of the city of St. Louis, in the Stateof Missouri, have invented certain new and useful Improvements in Car-Trucks, of which thefollowing is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification.

Our invention relates to that class of cartrucks wherein provision ismade for removing the axles and j ournal-boxes in a directionlengthwise-of the side frame. It has heretofore been proposed to soconstruct the ends of the side frames as to permit the axles,with thewheels, of course, and the journal-boxes to be removedwithout having toraise the frames vertically until they clear the axleboxes--as, forinstance, in Figure I of Patent No. 604,608, dated May 24, 1898,removable bolts 15, that form the outer ends of the side frames, areprovided for this purpose, so that by removing the bolts and jacking upthe side frames until the pressure on the axleboxes is relieved theaxles and boxes may be removed in the direction lengthwise of the sideframes, Whereas with the construction shown in Fig. IV of said patentthe side frames would have to be jacked up until they would clear theaxle-boxes before the latter can be removed. v

The object of our invention is to provide a strong, durable, andeffective construction of the class stated and one which is not liableto get out of order or to be rendered unsafe by use.

'Our invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Fig. I is a detail side view illustrative of our invention. Fig. II is afront view of the retaining-bar, part of the end of the side frame beingshown, the bar not being elevated to its raised position or the positionit 'occupies when in use. Fig. III is an enlarged detailV sectional Viewtaken on line III III, Fig. II, the retaining-bar being shown in itselevated position. Fig. IV is a perspective view of the retaining-bar.Fig. Vis a detail top View of the lower arm of the side frame. Fig. VIis a perspective View of the washer. Figs. VII to X, inclusive,represent a modification, Fig. VII being a side view, Fig.VIII a topview of the upper arm of the side frame, Fig. IX a perspective view ofthe Aretainingbar, and Fig. X a vertical section taken through the armsof the Aside frame and through the retaining-bar and washer. Figs. XI toXIV, inclusive, represent a second modification, Fig. XI being a sideView, Fig. XII a perspective View of the upper arm of the side frame andthe upper end of the retaining-bar and washer, Fig. XIII a top view ofthe lower arm of the side frame, and Fig. XIV a perspective View of oneof the washers used in the modification.

- Y Referring to the drawings, l represents part of oneof the lside frames of a car-truck-such, for instance, as is shown in the patent referredto. Each end of the side frame has an upper integral arm 2 and a lowerintegraly upper arm 2 of the frame is provided with ashoulder 12,(clearly illustrated in Fig. III,) and the lower arm of the frame isprovided with shoulders 13. (See Fig. V.)

When the axle-box and spring have been placed in position, the bar 6 isplaced with its lower end over the arm 3 of the frame, the flanges 11straddling the arm behind the shoulders 13. Being moved to a verticalposition, the bar is now raised until its anges 10 straddle the upperarm of the frame behind the shoulder 12, las shown in Fig. III. A washer14 is now inserted between the bottom of the bar and the upper face ofthe arm 3 of the frame and acts to hold the bar in its elevatedposition, and a bolt 15 is inserted through perforations formed in thebottom of the bar, the washer, and in the outer end of the arm Sto holdthe washer in position. The bar is thus firmly held in place without anystrain being IOO exerted on the bolt or any removable part of thestructure, the strain being entirely taken up by the flanges 10 and 11and the shoulders 12 and 13, which form integral parts ofthe structure,so that there is no liability ot' the displacement of any part whichwould allow the bar to become loose or unanchored, and thus accidentalrelease of the axle-boxes is impossible.

If desired, a bolt 16 may be passed through the upper end of theretaining-bar and the4 outer end of the arm 2, as shown in Figs. I andIII, to take up any slight`- play that might exist,and thus prevent anyrattling of the parts. To prevent the bolt 16 from dropping out shouldthe nut become loose and to avoid any possibility of the bolt 15 jumpingout should its nut come o, we insert transverse pins 17 through the bar6, close against the ends of these bolts.

In Figs. VII to X, inclusive, we have shown a modification wherein asingle bolt 18 is employed in lieu of the bolts 15 and 16, and inasmuchas this long bolt cannot, in some instances, be removed in a verticaldirection on account of coming against the car-body we form a slot 20 inthe outer end of the arm 2 of the side frame and provide verticalflanges 21, between which the head of the bolt fits, so that when theaxle-boxes are to be removed it is simply necessary to raise the bolt 18until the washer 14 is released, and then by taking out the washer andallowing the retaining-bar to drop to release its upper end the bar andbolt can be taken out together. Inasmuch as the ends of the arms of thetruck-frame and the retaining-bar are the same (with the noted exceptionof the slot 2O and the flanges 21) in this modification as in thepreferred construction,we have given the parts the samereference-numerals.

In Figs.XI to XIV,inclusive,we have shown another modification. In thismodification the retaining-bar is of the same shape as in the other twoconstructions. The upper end or arm of the side frame is, however,formed with a slot to receive a downwardly-extending lug 22 on a washer23, and the arm is furtherprovided with shoulders 24,behind which thewasher 23 fits. l/Vhen the parts are in position, the lng 22 engages theupper end of the retainer-bar, as shown in Fig. XI,and this holds thebar from outward movement,while it is held from lateral movement by itsflanges 10 engaging the outer end of the arm, as in the preferredconstruction. The lower arm is also formed with a slot 24 to receive anupwardly-projecting lug 25 on a washer 26,this lu g engaging the lowerend of the retainingbar, thus holding this end of the bar from outwardmovement, while lateral movement of this end of the bar is prevented bythe flanges 11 engaging the end of the side frame, as in the preferredconstruction. The lower arm is also provided with a shoulder 28, behindwhioh the washer 26 fits. In this latter modification a bolt 27 isemployed that passes through the washers 23 and 26 and through theretaining-bar, as illustrated in Fig. XI. While in this lattermodification a bolt is depended upon through the medium of the washers23 and 26 and their lugs 22 and 25 to hold the retaining-bar fromoutward movement, yet the lateral movement of the bar is prevented byits flanges engaging the arms, so that to the extent of preventinglateral movement of the bar the bar and arms are self-acting and do notdepend upon a bolt or any removable part of the structure to preventthis movement, and to this extent our invention is embodied in thismodification in the same manner as in the preferred form ofconstruction.
